> your friends can volunteer information about you indirectly by using "smart lists"

I didn't even know about this, but it illustrates that merely signing up exposes you to potential privacy violations. We recently became aware of how much of a liability it is for employers to look at Facebook profiles, because they may learn intimate details about a person's sexual orientation, religion, politics, etc. The only solution is to never look.

Likewise, the only way to adequately protect your privacy is to never sign up on Facebook. BTW, this takes care of the employer problem, too.

Exactly. Even if you try data poisoning (making an account with fake details), people can still attribute details to your account unsuspectingly. And you can't stop them from doing it, either. Very few people realize this lack of control.

Didn't Facebook also keep 'shadow profiles' of people not on the platform? So even if you're not signed up but your friends have tagged photos of you etc, Facebook can still infer things about you.

Not sure if this is still the case.

They also collected the browsing history of non-users. Freaky stuff.
